Abstract: NOISE REDUCING BLOWER MOTOR HOUSING       MEANS FOR VACUUM CLEANER       OR THE LIKE          ABSTRACT OF THE DISCLOSURE           The disclosure concerns a housing for re-ducing the noise and exhaust air velocity of a bypass type blower motor, particularly a motor used for a a tank type vacuum cleaner.  The entire housing sits atop the lid of the tank of the vacuum cleaner.  The bypass type blower motor has a main, suction generating, centrifugal blower fan and a separate motor cooling fan.  Outlet from the main blower fan is into a first expansion chamber above the lid.  A spiral pathway baffle in the first expansion chamber defines a gradually increasing cross-section plenum which communicates from the fan to the outlet from the first expansion chamber. There is a tubular outlet from the first expansion chamber which is surrounded by a sound baffling cuff of foamed plastic material.  A cooling air inlet to the motor cooling fan and a separate cooling air outlet from the casing for the motor cooling fan are provided. A second expansion chamber communicates with the cooling air outlet from the casing for receiving the exhausted motor cooling air.  The second expansion chamber separates the inlet to the motor cooling fan from the outlet from the motor casing for the cooling air.  The outlet for the exhausted cooling air from the second expansion chamber faces in the same direction as the inlet to the motor cooling fan.  A cover passes over the cooling air inlet and outlet.  A baffle between the second expansion chamber and the cover separates the air flows to the cooling air inlet and outlet.

Abstract: ABSTRACT OF THE DISCLOSURE    An electrically-fired gun, of the type having a transverse sliding breachblock, has a recoil-operated mechanism for retracting the firing pin electrode tip behind the face of the breachblock during its operating and closing movements.  A movable weight is connected by a rocker arm to the firing pin assembly, and is normally latched in place to hold the electrode tip in a retracted position. Manual release of the latch allows a spring to extend the electrode tip into a firing position. Recoil of the gun on firing results in a movement of the weight that retracts the electrode tip, and the parts are automatically re-latched in this position.

Abstract: Internal Combustion Engine Abstract An improvement to an internal combustion engine (10, 90) having a fuel system for feeding a fuel-air mixture to the combustion chambers which utilizes ammonia gas as an auxiliary fuel which is partially dissociated and added to the fuel-air mixture of the engine (10, 90).  The dissociated ammonia allows the engine to have its fuel-air ratio leaned down well below the misfire limits of hydrocarbon fuel and air to thereby improve the mileage of a vehicle and re-duce certain pollutants in the exhaust of the engine. The ammonia is stored in a liquefied state under pressure in a storage container (24, 98) and is fed to a dissociator (28) including a heater (30, 106) using heat from the engine's exhaust and a catalyst chamber (31, 107) and is then fed to the engine (10, 90).  The partially dissociated ammonia being fed to the engine is metered simultaneously with the changing of the fuel-air mixture and is controlled to lean the normal fuel-air mixture down.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved process is provided for preparing acyloxysiloxanes.          The acyloxysiloxanes are prepared by conducting an aliphatic carboxylic acid in vapour form upwards from the bottom of a column countercurrent to the flow of chlorosilane, in which the carboxylic acid is introduced into the column at such a rate that the carboxylic acid does not exceed 1.3 mol per gram of Si-bonded chlorine in the column, while introducing up to 10 percent by weight of water based on the weight of the carboxylic acid into the column and removing the acyloxysiloxane from the bottom of the column.  The process is carried out in the absence of iron or iron complexing agents, is conducted in the absence of solvents, with very short reaction times with excellent yields of acyloxysiloxanes.  These products may be mixed with diorganopolysiloxanes to prepare compositions storable under anhydrous conditions but which cure upon exposure to water to elastomeric solids.

Abstract: Abstract An improved ECC method and system are disclosed for corrrecting either a random single-bit error, or alternately, a multi-bit error in one byte of a data word from a single syndrome byte.  The improvement involves determining the location of the multi-bit error in successive data words which result because of a failure in one of a plurality of failure independent storage units employed for storing a block of multi-byte words.            The location of the defective byte position is deter-mined by summing each non-zero syndrome byte that is developed for each multi-byte word that is processed to produce a summed syndrome byte .SIGMA.S?0.  This summed syndrome byte is then employed to generate a set of vectors which are positionally related in an m-sequence to the summed syndrome byte.  A block syndrome byte, developed during the processing of a number of words and representing the sum modulo-2 of the error pattern in each word of the block, is compared to each of the set of vectors.  The position of the vector relative to the summed syndrome byte compared to the block syn-drome bytes then provides an indication of the byte position in each word which is in error.  With the defective byte position identified, the individual syndrome bytes for each word are then employed to develop for each word the correct error pattern for the defective byte position of each word.

Abstract: Abstract of the Disclosure In a telephone switching facility, line circuits are arranged in groups, each including a local ringing battery bus, and a universal high level signal generator (UHLSG) for providing ringing and other high level signals to the line circuits via the local ringing bus.  Each generator is responsive to address signals from a controller in the switching facility to generate selected high level signals.  The UHLSG includes a switching bridge driven by a width modulated signal stream of periodically occurring pulses having assertion times suitable for developing a high level signal across a network at the output of the switching bridge.  The width modulated pulses are generated from period and time signals.  The period signal occurs once with each sequence in repetitively generated data byte sequences.  The time signal occurs with correspondence between a selected stored data byte and an instant one of the data bytes of the sequence.  A plurality of the stored data bytes are arranged in ranges in a storage circuit.  One bit in the last data byte in each range causes the storage circuit's next readout to be from the beginning of a range as directed by the controller in the switching facility.                             - i -
